General description:

LSY three-phase-integrated current transformer is fit for be installed at the three-phase bushings of the ring switchgears and the switches on the wire poles. It is used to the measurement and protection of the three-phase current and the zero-sequence current for the three-phase bushings and the zero sequence current for then loops of the several cables.

The core and secondary windings are vacuum poured by high quality epoxies resin in the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance.
